Live Feed Out
Display live feed SD or HD video and audio straight out of the camera to a TV, handheld viewer, or video transmitter. Allows viewing a live video signal during preview, recording, and playback of saved files.

Upside Down Mode (UPd)
Now you can take videos and photos with the camera mounted upside down without having to rotate the files later. In UPd, all videos and photos will be saved to your SD card right-side up.

One Button Mode
One Button Mode simplifies recording video and photos with your HD HERO. With One Button Mode, your camera will start recording video or photos automatically when you power the camera 'ON' and will only stop recording when you power the camera 'OFF'. The shutter button is deactivated in One Button Mode. You can only turn the camera on and off, making it the perfect setting for loaning it to friends or newbies.

Display battery life, camera mode, and recording status icons on your live feed video signal with 'On Screen Display' turned on, or turn it off to transmit only the video without any status icons.
